Great replacement for the SMRTFT NÜOBELL if you live in Europe. I ordered these dumbbells, HG40 2.0, on a Friday evening and had them delivered the following Wednesday. This was incredibly fast and I was super impressed. Once I unboxed, I was a little shocked not to see any instructions on how to assemble anything, but it was VERY easy to just look at the parts, use a little common sense, and I got it all together in about 5-10 minutes. Easy peasy. The only downside was that one of the end caps was broken. However, this company is incredible! I snapped a picture of the broken piece, e-mailed them and within 2 hours I had a reply back. They apologized for the inconvenience and assured me a replacement part would be shipped the following morning. It has only been a day so I am sure the piece will be here very soon. I do not hold this against them, as things like this happen and patience is key. I was able to get a workout in using the dumbbells and I absolutely love them. They feel just like real dumbbells. The grip is awesome. The gnarl is good even with sweaty hands. There is very little, to almost no slip in between the plates and I really like that. I do wish the bases that hold the individual dumbbells was made to at least feel like a better quality. They feel light and cheap. As of right now, those two things are the only thing that I feel like could ever break out of all of the pieces. I am overall very pleased and can’t wait to see how well they hold up over time!
